Browsing through the net I've seen some interesting POV (Persistance of Vision) projects using the Atmega 168.

Has anyone worked on a POV project with the arduino?

I'm currently working on a performance piece and think it would be a nice touch to send some cues to the performers using POV, unfortunately, at the moment I don't have enough free time to read all the theory, documentation, etc. to start from scratch, but would really appreciate it if someone could give me pointers or a head start and then invest time on this.
